A 12,000-square-foot spec home featuring a floating shark tank hit the market today for $35 million, The Real Deal has learned.

The Beverly Hills home, built by developer Ario Fakheri, includes seven bedrooms, 11 bathrooms, a spa and gym, and of course, a shark tank. The floating saltwater tank contains at least seven stingrays, three different kinds of sharks, a starfish and three yellow tangs.

There’s also a living wall in the home created by Habitat Horticulture, the landscape architecture firm that also built the living wall at the San Francisco Museum of Modern Art. The wall was built with titanium steel, and features coral bells, spike moss and button ferns.

Sam Real of Nest Seekers has the listing.

In Los Angeles, developers have increasingly turned to extravagant amenities as a way to lure multi-million-dollar buyers. Bruce Makowsky, one of L.A.’s most well-known spec home developers, included a Louis Vuitton-designed bowling alley and a crocodile skin-clad elevator in his recently relisted $188 million estate in Bel Air.

Meanwhile, Nile Niami threw in 170 bottles of Cristal champagne, an array of luxury cars — including a gold Rolls-Royce Dawn coupe — and three Damien Hirst paintings when he initially listed “Opus,” a 20,500-square-foot mansion in Beverly Hills, at $100 million. (Just a month after listing, Niami chopped $15 million, along with artwork and cars, from the offer.)
